I liked the strat explanation, best Riven guide ive read so far :)
Ill try the W->E->Q sequence, it looks solid. About the items im still looking for the champ's core gameplay and adapt my usual favored AD item build accordingly

My item build looks like this:

Dorans Blade > Boots > The Brutalizer > Ionian Boots > Giants Belt > B.F. Sword > Bloodthirster > Youumuu's Ghostblade > Sunfire Cape > The Black Cleaver

with the CDR and the ARP items plus the Passiv & AD Damage you will rock the **** out of the enemys. I like this champ :]

I like this build, the runes really help out her early game, though I prefer shield over blade for the health regen, the life steal doesn't cut it. I think its also important that you put in BC or BT in for your build as strongly suggested optional items. I feel like this build doesn't give you enough AP.

I went shield > boots > brut > qss (there was a mal doing major damage) > BC > mallet > ghostblade. I never got to finish my atamas as it stopped there. I think you should include some items like qss in your build ;)

I gave this build a shot and I enjoyed it. I started with boots + 3hp, so i could be a bit more aggressive (was in lane with band). Rushed wriggles instead of cd boots. went 12-4-9.
